Chapter 28 : Caring for Clients With Heart Failure Questions
Question 1 of 5
The nurse is administering captopril to a client with a diagnosis of heart failure. What type of medication does the nurse infer the client is taking?
Correct Answer: A
Rationale: Captopril is an ACE inhibitor. Although the other medications may be used alone or in conjunction with other medications, the ACE inhibitor is a standard medication used in heart failure unless not tolerated by the client.
Question 2 of 5
A client is awaiting the availability of a heart for transplant. What option may be available to the client as a bridge to transplant?
Correct Answer: D
Rationale: VADs may be used for one of three purposes: (1) a bridge to recovery, (2) a bridge to transport, or (3) destination therapy (mechanical circulatory support when there is no option for a heart transplant). An implanted cardioverter-defibrillator or pacemaker is not a bridge to transplant and will only correct the conduction disturbance and not the pumping efficiency. An IABP is a temporary, secondary mechanical circulatory pump to supplement the ineffectual contraction of the left ventricle. The IABP is intended for only a few days.
Question 3 of 5
A client with heart failure reports not having had a bowel movement in 2 days. Why would it be important for the nurse to obtain a prescription for a stool softener?
Correct Answer: A
Rationale: Avoid activities that engage the Valsalva maneuver, such as straining with bowel elimination or using the arms to pull and reposition oneself. The Valsalva maneuver increases intrathoracic pressure, reduces right atrial filling, triggers tachycardia, and increases blood pressure. The client's discomfort would be increased if hemorrhoids or a rectal fissure developed but would not engage the Valsalva maneuver. It is not necessary for the client to have a bowel movement on a daily basis.
Question 4 of 5
A client diagnosed with pulmonary edema has a PaCO2 of 72 mm Hg and an oxygen saturation of 84%. What method of oxygen delivery would best meet the needs of this client?
Correct Answer: A
Rationale: The client's respiratory status is severely compromised and has developed signs of respiratory failure. When respiratory failure occurs, the client is intubated and oxygen is administered under continuous positive airway pressure or with mechanical ventilation with positive end-expiratory pressure. A face mask, cannula, or Venturi mask will not deliver the concentration or ventilatory support that an endotracheal tube with mechanical ventilation will provide.
Question 5 of 5
A client develops cardiogenic pulmonary edema and is extremely apprehensive. What medication can the nurse administer with a health care provider's prescription that will relieve anxiety and slow respiratory rate?
Correct Answer: D
Rationale: Morphine seems to help relieve respiratory symptoms by depressing higher cerebral centers, thus relieving anxiety and slowing respiratory rate. Morphine also promotes muscle relaxation and reduces the work of breathing. Furosemide is a loop diuretic and will decrease fluid accumulation but will not reduce anxiety. Nitroglycerin will promote smooth muscle relaxation in the vessel walls and will relieve pain but not reduce anxiety. Dopamine is an inotrope that will increase the force of ventricular contraction but will not alleviate anxiety.
